Here’s a quote from an article in the Tehran Times:

What to do if you don’t like school

Another good idea is to write down your feelings about school in a journal. You can use a journal or diary or just write in an ordinary notebook. It’s a great way to let out emotions that may be stuck inside you. And you don’t have to share what you’ve written with others.

But if you’re a kid who’s the outcast at school, be careful what you do with that notebook! You don’t want to end up like Harriet the Spy, with everyone reading what you’ve written about them! I remember being completely distressed as a 7th grader when I lost a wonderful notebook. I hadn’t written anything nasty about my classmates, but I was just dying thinking someone might reveal embarrassing things I’d written about myself!
